** There have been three spacewalks this month at the station including one today:

… Expedition 53 Commander Randy Bresnik and Flight Engineer Joe Acaba of NASA conducted a spacewalk Oct. 20 to continue upgrades to and maintenance of station hardware. It was the third spacewalk in two weeks for Expedition 53 crewmembers outside the Quest airlock. During the excursion, Bresnik and Acaba replaced a failed camera light on the new Latching End Effector “hand” on the Canadarm2 robotic arm, installed a new high definition camera on the starboard truss of the complex, replaced a fuse on the Dextre Special Dexterous Manipulator attachment for the arm and removed thermal blankets from two spare electrical routing units for future robotic replacement work, if required. It was the fifth spacewalk in Bresnik’s career and the third for Acaba.
